"Compilation error: 'lcd' was not declared in this scope"

Simple "Hello World" but instead of using Serial.print, I want to print to a 1602 Keypad Shield.
So, I changed Serial.print to lcd.print. The error in the subject line is where I'm stopped, I don't know how to declare lcd or where.
Thanks for your input, DougerPreformatted text
Here is the sketch.

#include <LiquidCrystal.h>

void setup() {
Serial.begin(9600);
}
void loop() {
lcd.print("Hello World!");
delay(1000);
}

The compiler is not lying. There is no object named lcd in the sketch

Have you looked at the examples that came with the LiquidCrystal library ?

The library you used, LiquidCrystal.h, has few examples.
You can see how to declare lcd object in EVERY library example.
